The Wehrli Top Outlet Billet Thermostat Housing and Upper Coolant Pipe Kit is made for 2001–2005 Chevrolet 6.6L LB7/LLY Duramax engines and replaces the OEM upper radiator hose and coolant return pipe. By rerouting coolant upward and forward from the thermostat, it improves access to driver-side fuel components and creates room for larger aftermarket turbochargers. The kit includes the coolant pipe, silicone boots and t-bolt clamps, and is CNC-machined billet aluminum with a custom two-stage powder coat finish.
